Power System Remounted

After quite a while of hacking I'm approaching feature completeness. So I spent most of the day yesterday cleaning up the installation technique. There's now a cabinet for the computer, and the electronics are mounted away from the floor for cleanlyness. And the batteries all all solidly mounted to the floor with proper battery mounts.

The much cleaned up installation.

There's still some cable management to be dealt with. And my Arduino based voltage measuring circuit is not fully hooked up yet.

Inverter hooked up and outlets installed

The second part of the inverter charger is the inverter. I now have nice outlets where I can plug in most any power tool.  One is up front and the other is in the back. 

The 110V power socket at the rear of the trailer. (The wood wall is the back ramp, closed.)  

The forward outlet next to the window. 

The losses in the inverter are a little bit higher than I had hoped. When in charge only mode it appears to draw 195mA. And when inverting it consumes 1.2A. Under load I think the losses drop to a little under 1.0A. At least there is a DC-OFF switch position which does not load the batteries. 

Backup Sun Enabled

In case there's not enough sun to keep things going. (Or I haven't had time to get the rest of the solar panels up.) I now have the option of using shore power. The inverter charger also enables 110V outlets too, but more on that later.

Added the receptical to the side of the trailer. 

The inverter charger pushing 23 Amps into the batteries. 

The net result is that I can now plug in the trailer if I want to top off the batteries. The inverter charger I have is the Tripp Lite 750 RV model.
